[exim] using aux acls -- why is control not passing correctly?

[snowcrash+exim-users]

hi,

i've Exim 'talking' to remote clamd/spamd daemons over TCP,

        av_scanner = clamd: 10.0.0.105 3310
        spamd_address = 10.0.0.105 783

i'm trying to clean-up my eximconf using aux acls.

problem is, as config'd below, exim submits OK to CLAMD, but never
submits again/subsequently to SPAMD.

i suspect i may NOT be using 'endpass' correctly ...

any suggestions as to why my submit to SPAMD never occurs?

thanks!

fyi, in my exim.conf, i've,

        addresslist no_virus_scan  = [EMAIL PROTECTED]
        addresslist no_spam_scan   = [EMAIL PROTECTED]


and, in my DATA acl, i've

        accept
                 !senders        = +no_virus_scan
                 endpass
                 acl             = aux_acl_virus
        
        accept
                 !senders        = +no_spam_scan
                 endpass
                 acl             = aux_acl_spam


where, later, i've def'd

aux_acl_virus:

    deny
             set acl_m9      = REJECT[virus] : ($malware_name)

             log_message     = EXIM: $acl_m9
             malware         = *

    accept

             set acl_m9      = spam
             condition       = ${if !eq {$acl_m0}{accept}{true}}
             control         = fakereject
             logwrite        = :reject: Rejected spam (score

    deny     message         = REJECT[spam] - \

             spam            = nobody:true
             condition       = ${if > {$spam_score_int}{20} {1}{0}}

    warn
             message         = X-SpamLevel: \
